HAND-STAMP.

SPECIFICATION formingpart of Letters Patent No. 251,667, dated December 27, 1881. v Application filed October 26, 1881. (No model.)

To all whom it may concern Be it known that I, CHARLES C. WILsoN, a citizen-of the United States, residing at Washington, in the county of Washington and District of Columbia, and useful, Improvements in Hand-Stamps; and I do hereby declare the following to be a full, clear,'and exact description of the invention, such as will enable others skilled in the art to which it appertains to makeand use the same, reference being bad to the accompanying drawings, and to the letters or figures of reference marked thereon, which form apart of this specification. g I y This invention relates to improvements in hand printing-stamps,

between the act of inking and printing, and are known in the market as self-inking handstamps; and the object of the invention is to provide a self-inking hand-stamp having a dieplate containing the fixed matter, also an arrangement for dating, and in addition to that a series ofnumbering-wheels arranged to consecutively number the impressions of the die plate, so that letters, documents, and the like may be at one operation properly stamped, dated, and consecutively numbered in a very simple and convenient manner; and to that end the invention consists in a self-inking handstamp, upon the oscillating die-plate of which is secured a seriesof number-wheels, arranged to consecutively record the number of articles stamped, as will be hereinaftermore fully described, and particularly pointed out in the claims.

In the accompanying drawings similarletters of reference marked thereon indicate like parts of the invention. I

Figure 1 is a side elevation of my improved stamp; Fig. 2, an end elevation, partlyin secframe, D, to the ends tion, through the line 00 w,- Figs. 3 and 4, details of construction, and Fig. 5 a modification of the number-changing mechanism.

A is the handle, into which the central'guide shaft, B, recedes, it normally'being forced outwardly by the spiral spring 0.

To the handle A is secured a rectangular of the legs of which is pivoted the die-plate E by means of the pivotscrews .9 e.

have invented certain new I and particularly to that, class of stamps wherein the die partially rotates 1 To the shaft B, and forming part of it, is attached the rectangular guide-frame F, having slotted guideways f in each leg, through which the pivots e 6 pass.

The die-plateE is provided at one end with a mutilated gear, 6, which, when the handle is depressed, engages with the studs 0 and causes a half-revolution of the die-plate. To the other end of the die-plate is attached a projecting guide, a, which slides in the guideways a a and serves to keep the die-plate in a horizontal 1 plane at all times except when being partially rotated by the studs 0 and to facilitate this a portion of the guideway a is cut away about -midway of its length to allow the guide 0 to make a half-revolution at that point.

As shown in Fig. 1, the stamp is in its normal position, with the die-plate in contact with the inking-pad K. By depressing the handle which forces the frameD downward, the dieplate is also forced down in a horizontal position until the gear 6 which causes the die-plate to make a half-revolution and then resume its horizontal position and continue the downward movement until it comes in contact with the article to be printed on. By releasing the pressure on the handle a movement the reverse of the above takes place, and the die resumes its normal position.

Secured in a suitable manner to the die-plate is a frame, G, in about the center of which is journaled a shaft, H, upon which is mounteda series of numbering-wheels, h h W 71?, each wheel printing from 9, inclusive, and having their printing-faces extending through the die plate, so as tojustify with the matter on said plate. These wheels are so arranged that each complete movement of the die-plate moves the units-wheel one tooth or point, and each complete revolution of the units-wheel moves the tenswheel one point. Each revolution of the tens-wheel moves the hundreds-wheel one point, and so on to the end of the series, in which as many wheels may be used as are desirable.

To one end of the frame G is pivoted a vibratinglever, I, provided with a pawl, i, which engages with the ratchet-teeth 70 on the unitswheel h, and the vibratory play of the lever I at a time. The lever I terminates in a pin, Z,

engages with the studs 6 which is arranged toengage in a V-shaped indentationm, in theilower end of the thumb lever N, so as to hold the pint and lever I, whereby the movement of the die-plate will cause the pawl t to engage a tooth on the ratchet and revolve the units-wheel one point.

In pressing the handle down to; print, the die-plate follows, and with it the lever I, the pin end of which is held by the in'dent at until the pawl slips over a tooth of the ratchet,w.-henbeing'completed'and the newnumber brought into proper place at the moment the die-plate comes in'contact with theink-pad. Thus it will be seen that in the ordinary operation of the stamp each time itis used a consecutive number is printed; If, however, it becomes necessary to, repeat any. number two or more times, it may readily be done by pressing on the upper part of the thumb-lever. N, which forces the indent n to be withdrawn frointhe j path of the pin l, and there being nothing, to

operate the lever and pawl thetnumber remains 2 unchanged. ByreleasingtheleverN the spiral, spring 0 forces it back into the path of the pin 1 and lever I, and. the units-wheelis operated to number consecutively as before.

In Fig. 5 is shown a modification in which thepin is;put onthe thumb-lever and the indent on the operating pawl-lever.

Having thus fully described my invention and the operation of the same, what I claim as new and useful, and desire to secure by Letters Patent of the United States, is- I 1. In a hand-stamp, an oscillating die-plate providedwith acon secutive-numberin g device, combined with mechanism, substantiallyas described, by which the number will be changed in the operation of the stamp, as set forth.

2. In a hand-stamp, an oscillating die-plate provided; with. numbering-wheels, combined with a cam adapted, substantially as described, to be thrown out ofgear at will, as set forth.

3. Ina self-inkin g hand-stamp, an oscillating die-plate and consecutive-numbering device,

' in-combination-with a pawl and ratchet operating said numbering device, substantially as.

Set to rth.

In a hand-stamp, an oscillating die-plate provided'with a seriesot numbering-wheels, in-

combi-nationwith alever operating said'wheels, said lever being operated byacamrordetent mounted on theistationary frame, as set forth.

5. In ahand-stamp, the combination, with the oscillatingdierplateand con-secutive-num-.

bering wheels, of the levers I and Ni andpawl t, as andfor the-purpose set forth.
